feat(snippets): single SupportedLanguages component over vended JSON

Replaces the standalone LanguageTable snippet with one
`<SupportedLanguages>` component. Doc authors drop it anywhere they
need to list languages and pass props that mirror the
`GET /v3/languages` contract:

- `mode`: `inline` (default, comma-separated codes) | `bullets` |
  `table` (the existing interactive sortable/filterable table).
- `resource`: matches a /v3/languages resource (`translate_text`,
  `translate_document`, `voice`, `write`, `glossary`, `style_rules`,
  `translation_memory`).
- `feature`: API feature key (`style_rules`, `writing_style`, `tone`,
  `auto_detection`, `glossary`, `tag_handling`, ...).
- `direction`: `source` | `target`.
- `includeBeta`: bool.

The snippet inlines a `RESOURCES` object holding the verbatim
/v3/languages responses, refreshed by the hourly workflow via
`scripts/generate_language_table.py`. Mintlify's snippet sandbox does
not honour ES module imports, so the data has to ship inside the
snippet file itself. Operators not supported by the sandbox (`in`,
notably) are avoided.

Adds `data/v3-languages/translation_memory.json` shaped like a
/v3/languages response so the real API response can drop in unchanged
once Translation Memory ships as a resource.

Wires the regen step into `.github/workflows/refresh-v3-languages.yml`
so each hourly refresh produces a single PR containing both the
updated JSON and the regenerated snippet.

Migrates the two `docs`/`api-reference` places that hand-typed feature
language lists to use `<SupportedLanguages>` instead. The
quality-estimation page keeps its manual list for now because QE is
not exposed as a /v3/languages resource yet.

             This PR is rewritten in place on each run: if the vended responses change again
             before merge, the branch is force-pushed with a new single squashed commit so the
             diff against `main` always reflects the latest API state. If a run finds the
             responses identical to what is already on the branch, the branch is left untouched.
             If a run finds the responses match `main` (e.g. the PR was merged), this PR is
             closed and the branch deleted automatically.
